Interspinous process implant

A method of placing a spinal implant at a treatment site comprising:

• providing a spinal implant in a first closed configuration, said spinal implant comprising:
• a main body having a central bore and a longitudinal axis extending between a proximal end and a distal end;
• a proximal anchor comprising a nut received on an outer surface of the main body;
• a distal anchor comprising:
• a first wing having a first inner end and a first outer end, and a second wing having a second inner end and a second outer end, wherein said first inner end is rotatably connected to said second inner end at a first pivot point;
• and
• an internal plunger having a proximal end and a distal end, said internal plunger housed within the central bore of the main body, said distal end of the internal plunger connected to both a proximal end of a first linkage and a proximal end of a second linkage at a second pivot point,
• placing the spinal implant in a patient at a desired treatment site;
• and
• sliding the internal plunger distally along the longitudinal axis to rotate the first outer end of the first wing and the second outer end of the second wing distally to a second open configuration.

A spinal implant comprising:

• a main body having a central bore and a longitudinal axis extending between a proximal end and a distal end;
• a proximal anchor comprising a nut having a textured distal surface, said nut received around an outer surface of the main body;
• a distal anchor having a first closed configuration and a second open configuration, said distal anchor comprising:
• a first wing having a first inner end, a first outer end, a first substantially planar top surface, and a first base surface at the first inner end, the first top surface extending at an angle of about 35 to about 45 degrees relative to the first base surface, and
• a second wing having a second inner end, a second outer end, a second substantially planar top surface, and a second base surface, the second top surface extending at an angle of about 35 to about 45 degrees relative to the second base surface,
• wherein said first inner end is rotatably connected to said second inner end at a first pivot point;
• and
• an internal plunger having a proximal end and a distal end, said internal plunger housed within the central bore of the main body, said distal end of the internal plunger connected to both a proximal end of a first linkage and a proximal end of a second linkage at a second pivot point,
• wherein longitudinal distal movement of the internal plunger rotates the first outer end of the first wing and the second outer end of the second wing distally to transition from the first closed configuration to the second open configuration, and longitudinal proximal movement of the internal plunger folds the first wing and the second wing proximally to transition from the second open configuration to the first closed configuration.
